Solve:

A square with a side length of 10 centimeters has twice the area of a square with a side length of 5 centimeters.

Create convincing evidence that this claim is or is not true:

Convincing evidence checklist:

Includes drawings of the objects (lengths are labeled)

Words are used to explain the meaning of all numbers and calculations

All calculations are clear and easy to follow

Your stand is demonstrated using multiple methods. (drawings, calculations, sentences)

Challenge: Draw a square that has an area that is very close to twice the area of a square with a side length of 5 centimeters
